Cattle King is a 1963 American Western film directed by Tay Garnett.

Caught on opposite sides are Sam Brassfield, who builds fences to protect his grass land, and Clay Mathews, a cattle baron determined to keep an open range.

Both men argue their case before the cattlemen's association to President Chester A. Arthur, who happens to be in Cheyenne for a visit.

Brassfield proposes marriage to Sharleen Travers, who runs a neighboring ranch with her brother Harry.

A while thereafter, the hired gun Bodine shoots and wounds the unarmed Harry, then kills Sharleen in cold blood.
